His method has been to monitor population numbers in relation to river flow in March, when the juvenile fish emerge. He concludes that environmental conditions change each year and modify river flow, positively or negatively affecting survival rates. This information throws light on a long debate within ecological theory about the mechanisms that regulate the size of animal populations. http://www.physorg.com/news171734736.html Biology Wed, 09 Sep 2009 17:20:01 EST news171734736 (PhysOrg.com) -- A new study finds that large-scale farming projects can erode the Earth's surface at rates comparable to those of the world's largest rivers and glaciers. http://www.physorg.com/news171121178.html Space & Earth Wed, 02 Sep 2009 15:00:10 EST news171121178 Steep reductions in the abundance of fish, shellfish, and other aquatic fauna in recent centuries are not restricted to animals that live in the sea: historical records show that species in rivers and lakes worldwide also experienced sharp declines. Yet the significance of these declines in freshwater species is frequently overlooked by natural resource managers, according to an article in the September 2009 issue of BioScience. http://www.physorg.com/news171007079.html Biology Tue, 01 Sep 2009 07:10:01 EST news171007079 Water managers and the White House signed a crucial contract Thursday that promises a much-needed infusion of federal dollars for the Everglades. http://www.physorg.com/news169483473.html Space & Earth Fri, 14 Aug 2009 15:46:23 EST news169483473 (PhysOrg.com) -- Using satellite data, UC Irvine and NASA hydrologists have found that groundwater beneath northern India has been receding by as much as 1 foot per year over the past decade - and they believe human consumption is almost entirely to blame. http://www.physorg.com/news169302846.html Space & Earth Wed, 12 Aug 2009 13:35:33 EST news169302846 The nation's cleanest beachwaters are along the upper half of the Atlantic seaboard, in Virginia, Delaware and New Hampshire, a national environmental group said Wednesday. http://www.physorg.com/news168198589.html Space & Earth Thu, 30 Jul 2009 19:10:01 EST news168198589 For avid fishermen and anglers, the largemouth bass is a favorite freshwater fish with an appetite for minnows. A new study finds that once they evolved to eat other fish, largemouth bass and fellow fish-feeders have remained relatively unchanged compared with their insect- and snail-eating cousins. As these fishes became top predators in aquatic ecosystems, natural selection put the breaks on evolution, say researchers. http://www.physorg.com/news168016891.html Biology Tue, 28 Jul 2009 16:40:06 EST news168016891 By substituting a single atom in a molecule widely used to purify water, researchers at Sandia National Laboratories have created a far more effective decontaminant with a shelf life superior to products currently on the market. http://www.physorg.com/news167406771.html Chemistry Tue, 21 Jul 2009 15:10:01 EST news167406771 A plan to restore salmon runs on California's Sacramento River also could help revive killer whale populations 700 miles to the north in Puget Sound, as federal scientists struggle to protect endangered species in a complex ecosystem that stretches along the Pacific coast from California to Alaska. http://www.physorg.com/news166022139.html Biology Sun, 05 Jul 2009 14:16:25 EST news166022139 (PhysOrg.com) -- South Australians living on the coast, near the River Murray and in metropolitan Adelaide are more likely to get skin cancer than their inland cousins. http://www.physorg.com/news165160647.html Medicine & Health Thu, 25 Jun 2009 14:58:08 EST news165160647 Later this week, researchers at Stevens Institute of Technology will equip the sloop Clearwater with instrumentation that will provide real-time transmission of position, time, surface water temperature, salinity, and dissolved oxygen concentrations in the northern area of the Hudson River. http://www.physorg.com/news164991668.html Space & Earth Tue, 23 Jun 2009 16:02:07 EST news164991668 Khoo Teng Chye, the amiable chief of Singapore's water agency, says he has been sleeping soundly since taking office five years ago. http://www.physorg.com/news164816013.html Space & Earth Sun, 21 Jun 2009 19:20:01 EST news164816013 (PhysOrg.com) -- Reductions in the flow of the Apalachicola River have far-reaching effects that could prove detrimental to grouper and other reef fish populations in the northeastern Gulf of Mexico, according to a new Florida State University study that may provide new ammunition for states engaged in a nearly two-decade water war. http://www.physorg.com/news164628531.html Space & Earth Fri, 19 Jun 2009 11:10:30 EST news164628531
